Does the wrong power input for a voltage converter affect the appliance?

I got this waffle maker from America for use in the uk and somehow I discovered a burnout and smoke was coming out the adapter does this mean the appliance is unharmed and the adapter (which is a max of 100 w and the wafflemaker of 1200 w) took the burn out coz I unscrewed the wafflemaker to look at the circuit board and nothing was burnt|||The Wafflemaker is fine. The transformer is gone, simplt becasue you overloaded it. You need to get a converter with a transformer that can handle 1200W, or a solid state one for heating type appliances.|||The adapter is certainly wrecked

You would have to be very unlucky to damage the appliance - The input 230v is safely isolated from the output 115v in normal operation..When you destroyed it, it should 'fail safe' so that your appliance never 'sees' 230v.



I guess you know that you cannot run a 1200w appliance from a 100w adapter but very probably it is only the adapter destroyed



EDIT

Just replace the adapter with one that is powerful enough. The waffle maker is *probably* fine|||You have leaned a lesson, always check the voltage is correct for the appliance you are using, some US electrical products can be used in the UK, they have dual voltage, but always read the instructions , if its says less than 220 volts don't plug it in as it will burn out... BTW The warranty is invalid so you can't return it.|||Too much could overheat it and burn random circuits and too little wont work and still messes it up for some reason i forgot
